Routeur Cisco 2600 series

Routeur Cisco 2600 series

  • Brancher le routeur électriquement, et connecter le cable console au routeur et à un PC. La démo suppose un PC fonctionnant sous Slackware Linux.
  • Vérifier les droits Linux:
    philb@core2:~$ sudo su -
    root@core2:~# ls -al /dev/ttyS0
    crw-rw---- 1 root dialout 4, 64 2010-01-19 13:34 /dev/ttyS0
    root@core2:~# vigr
    

    Modifier la ligne suivante pour s’ajouter au groupe « dialout »

    dialout:x:16:uucp,philb
    

    Penser à se deconnecter / reconnecter pour que les nouveaux parametres de groupes soient pris en compte

    root@core2:~# exit
    philb@core2:~$ exit
    

  • Configuration du port série
    root@core2:~# vim /etc/minirc._dev_ttyS0
    # Machine-generated file - use "minicom -s" to change parameters.
    pr port             /dev/ttyS0

    root@core2:~# exit
    
  • Connexion au routeur
    philb@core2:~$ minicom /dev/ttyS0
    
  • Allumer le routeur… Les lignes suivantes doivent défiler…
